Slava Pestov e76dce8aff Overflowing fixnum intrinsics now expand into several CFG nodes. This speeds up the common case since only the uncommon case is now a stack syncpoint 2009-07-16 18:29:40 -05:00
Slava Pestov 7e3fa45512 compiler.cfg.stack-analysis: fix unit tests for useless-blocks renaming and ##no-tco instruction 2009-06-30 23:17:33 -05:00
Slava Pestov 5bb235d38f compiler.cfg.checker: run if a variable is set 2009-06-05 17:32:12 -05:00
Doug Coleman 19d6285035 fix load error 2009-06-01 09:34:28 -05:00
Slava Pestov 692b479302 Split off local-optimization combinator into compiler.cfg.local, factor out CFG -> MR into compiler.cfg.mr, split off GC check insertion into a new compiler.cfg.gc-checks pass 2009-05-31 12:20:46 -05:00
Slava Pestov e04df76f60 Various codegen improvements:
- new-insn word to construct instructions
- cache RPO in the CFG
- re-organize low-level optimizer so that MR is built after register allocation
- register allocation now stores instruction numbers in the instructions themselves
- split defs-vregs into defs-vregs and temp-vregs

Slava Pestov 76d74c16af Fixing various bugs; alias analysis wasn't handling ##phi nodes, stack analysis incorrectly handled height-changing back edges and ##fixnum-*, clean up ##dispatch generation 2009-05-29 01:39:14 -05:00
Slava Pestov ecece1d08b CFG checker now checks consistency of successors and predecessors lists; fix long-standing bug in useless-blocks optimization 2009-05-28 02:49:51 -05:00
Slava Pestov f3688c9373 Better CFG checker 2009-05-27 18:58:14 -05:00
